Hello tjohnson1994,
Thank you for using the Apple Support Communities!
It sounds like you want to keep the iTunes mini player on top of all other windows so that you always have access to it. I will be happy to help you with this.
The way to do this is thru iTunes preferences. You can get to the Preferences by clicking on the Menu icon in the upper-left corner of iTunes. You can also open it by pressing the control and comma keys at the same time. Once Preferences is open, click on the Advanced tab. There should be a selection to "Keep MiniPlayer on top of all other windows". Make sure this is checked.

Have a great day!
